Technologies that transform and store renewable energy are crucial for creating a sustainable society, which is independent of fossil fuels. In this regard, electrochemical water splitting based on the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is an attractive technique for producing carbon-free hydrogen fuels. Additionally, rechargeable metal–air batteries (MABs) are another intriguing way for renewable energy storage through reversible oxygen reactions (OER and the oxygen reduction reaction, ORR). Herein, we comprehensively review bifunctional electrocatalysts for water splitting (HER and OER) and MABs (OER and ORR), particularly 2D carbon material-derived heterostructures. The synthesis and properties of 2D carbon materials and their energy conversion and storage mechanisms are discussed to highlight the bifunctionality of the heterostructures. Recent studies on bifunctional electrocatalysts based on 2D carbon-derived heterostructures are also reviewed.

Graphene is a two-dimensional single-atom carbon-packed material that possesses fascinating properties, including a large surface area, remarkable electrical conductivity, extraordinary intrinsic electron mobility, high Young's modulus, superior mechanical strength, optical transmittance, catalytic performance, and stability.

Unfortunately, both data acquisition and interpretation are not always straightforward and sometimes the data are not well reported and discussed, limiting their impact in the literature. In this perspective review, we critically analyse the contributions provided by different spectroscopic techniques, sometime supported by molecular modelling approaches, to unravel the nature of Ce(IV)-MOFs at any stage of their preparation and along their use (<em>i.e.</em>, post-synthesis treatments and under reaction conditions). A concise description of major results from the recent literature allows to provide basic insights associated to the applicability and limits of most used spectroscopic approaches, showing that more robust understanding of Ce(IV)-MOFs can be achieved when a broad spectrum of techniques are used in parallel, adopting similar conditions and following good practice rules.</div></div>","PeriodicalId":33573,"journal":{"name":"Nano Materials Science","volume":"7 6","pages":"Pages 761-772"},"PeriodicalIF":17.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145651778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of SPD on the microstructures, mechanical properties, and corrosion behaviors were generally investigated. The two SPD routes resulted in totally different microstructures. ECAPed samples processed at 150 ​°C exhibited a complicated multilevel structure (nm to μm) with mixed Zn equiaxed grains and lamellar-like eutectoid regions (Zn ​+ ​α-LiZn₄), and HPTed ones (25 ​°C) possessed a fully dynamically recrystallized (DRXed) microstructure with an average grain size below 0.4 ​μm. The tensile strength of the SPD samples could reach 500 ​MPa. Meanwhile, HPTed samples exhibited extraordinary fracture elongations higher than 100 ​%, because of a different grain boundary sliding deformation mechanism. HPTed samples and ECAPed samples displayed different corrosion patterns, and the former exhibited a much higher corrosion rate in Hank's solution, possibly due to the accelerated corrosion at grain boundaries.
